Primobolan test. The best steroids test kit on the market

We will use three different samples: GSO (Grain Seed Oil), MCT oil, and raw powder. Note that the initial colors may vary, but this does not necessarily indicate the presence of a hormone. To confirm the presence of a hormone, a UV test is required. Shine a 365 nm UV light on the glass ampoule, and observe the fluorescence. Different samples will exhibit different fluorescence colors, and you cannot determine if your sample contains a hormone without performing this UV test. Pay close attention to the fluorescence colors—if they match those expected for Primobolan, it is likely present.

Additionally, make sure you are using a genuine 365 nm UV light, especially if you did not purchase it from Labmax. Many counterfeit 365 nm UV lights are sold on platforms like eBay or Amazon, and using an incorrect UV light will make the test unreliable. When applying the sample, use only a small amount, as the test reagent inside the vials is minimal. You will notice significant differences in the results between samples based on MCT and GSO oils. Not all steroids will show such pronounced differences depending on the carrier oil—some will look the same regardless of the oil used.

This is a two-stage test: first, use Vial A to perform an initial test, and then confirm the results with Vial B, which contains a different test reagent. This dual-stage approach increases the reliability of the test.

The type of oil used as a carrier does not affect whether the sample will fluoresce if a hormone is present. However, the intensity of the fluorescence may vary depending on the oil, as different oils absorb and reflect light in different ways.

Just after dropping samples. Notice that sample with GSO oil is darker but at this point it is not indication of hormone presence until we do UV test.

No initial color change for raw powder in both vial A and B.
